World's First LNG-hybrid Tug Will Run mtu Gas Engines

The main propulsion system of the Sembcorp hybrid tug comprises twin 16-cyclinder mtu Series 4000 gas units which will provide a combined total power of 2984 kilowatts. The new engines are part of Rolls-Royce's Green and High-Tech program. Without exhaust gas aftertreatment they emit no sulfur oxides and only very small quantities of nitrogen oxide and particulate mass is below the verification limit. (Photo: Rolls-Royce)

A new liquefied natural gas (LNG)-hybrid tug—said to be the world's first—will be equipped with two mtu 16V 4000 M55RN gas engines from manufacturer Rolls-Royce.The harbor tug will be built by Sembcorp Marine Integrated Yard and operated in Singapore by Jurong Marine Services, a wholly owned subsidiary of Sembcorp Marine. The new LNG-hybrid tug is the first of 12 tugs that Sembcorp Marine plans to design and build to replace the existing diesel-powered ones between now and 2025.LNG as a fuel virtually eliminates sulphur oxide emissions

CMR Group’s chief technical officer, Patrice Flot, considers the current approach to sensing exhaust gas temperature (EGT) on high horsepower engine platforms and the capabilities provided by new digital technology. An EGT sensor measures the temperature of the engine exhaust gas to prevent damage to critical components such as the after treatment system, turbines and cylinder head exhaust valves. It can also be used inside the combustion chambers where hot gases are generated.

NGOs Call Upon EU to Effectively Regulate Shipping Pollution

From dangerous emissions in ports to hazardous scrapping on South Asian beaches, European shipping companies pollute and put people’s health and lives at serious risk. In light of the ongoing European Shipping Week and the failure of the International Maritime Organisation to find solutions, environmental experts are ringing the alarm bell and calling upon European policy makers to urgently adopt policies that effectively target the environmental performance of shipping. “Every year approximately 50,000 people in the EU die prematurely because of air pollution from ships. While all land-based sources have been gradually regulated in recent years we still face a lack of effective emissions control measures for ships,” says Daniel Rieger from NABU.

Ferries operated by Norden-Frisia AG have been serving the East Frisian island of Norderney for many decades. Navigation in these coastal waters poses special challenges: in some areas the waterway only leaves a few centimeters below the keel and the water contains a significant amount of swirled-up sand. A new sister ship of the double-ended ferry MS Frisia IV equipped with Voith Schneider Propellers (VSP) is to enter service in summer 2015. The shipping company again chose Voith Schneider Propellers as these are ideally suited for the specific operating conditions in shallow tidelands.
